TECHNICAL FIELD

The present invention relates generally to roof-top vehicle carriers and specifically to a carrier that includes a secure storage space and a detachable boat.

BACKGROUND OF THE INVENTION

Although many travelers and sports enthusiast carry boats on trailers or inside a vehicle, such as an SUV, car, RV, truck and the like, many simply tie the boat to the roof of the vehicle. Problems arise when carrying a boat on the roof of a vehicle. The boat may shift in transit and damage the vehicle exterior or come off completely and damage another vehicle on the road. Certain boats, such as those made of wood and other materials, are heavy and difficult to lift on and off the vehicle roof. Other boats are wider or longer than the vehicle roof top and may tip if not secured to the bumpers of the vehicle. Ropes or straps used to secure the boat to the bumpers obscure the vision of the driver. When a boat is stored inside the vehicle, space for passengers and storage space for equipment and gear are reduced or eliminated.

There are a number of existing ways to carry a boat on a vehicle roof. Simple, heavy duty bars and racks are standard on, or may be added to many sports vehicles to aid in carrying equipment and gear. Tying the boat to existing racks, while simple, is time consuming, and may not be adequate to prevent the boat from slipping—or the ropes may become untied and cause the boat to fly off the roof with tragic results in traffic.

Thule AB (Murmansgatan 126, 212 25 Malmö, Sweden) and Yakima Products, Inc. (15025 SW Koll Pkwy., Beaverton, Oreg. 97006-6056) make roof rack systems for most cars, trucks, vans, SUVs and RVs to transport boats and kayaks. These systems typically comprise horizontal bars that extend the width of the vehicle with padded supports that cradle a boat or kayak on the vehicle roof rack. While providing better attachment, these systems have drawbacks. Loading and unloading a boat from a vehicle using these systems is difficult and typically takes two people. If the boat is attached to a base along a side, hinges are typically used. Engaging and disengaging the hinges is difficult and requires a ladder in larger profile vehicles. Kayaks present additional problems. Kayak users sometimes cinch tie lines too tightly, which can cause hull damage to the kayak. are difficult to

Thule AB makes cargo boxes that attach to existing roof racks. Thule® cargo boxes are durable, side opening storage containers that are about 87″L×36″W×15″H. However, no storage space is typically included with boat or kayak rack systems for vehicles.

A need exists for an economical and cost-efficient lightweight boat sized to fit the roof-top of a vehicle that is securely fasted to the vehicle, but can be removed easily by one person. Combining such a boat with the ability to securely and safely store equipment and gear under the boat would be useful to travelers.

DISCLOSURE OF THE INVENTION

The present invention is directed to a boat and storage container attachable to existing roof racks on a vehicle. In an embodiment, the invention comprises a boat that fits atop and is securely attachably detachable to a roof top storage container such that the bow of the boat is toward the front of the vehicle roof and the boat/container creates an aerodynamic storage space.

The present invention is a storage device attachable to a vehicle roof rack that has a removable, relatively small, light-weight boat that serves as a waterproof durable cover. The storage device comprises a container, means for releasably attaching the container to the roof rack, and means for securely releasably attaching the boat in an inverted position to the container. The storage device comprises a base and at least two side walls that form the container. The walls may be attached to each other at a bow end. The storage device is oriented with the bow end of the boat and the container toward the front of the vehicle. The container is an open container that has a shape that generally conforms to the interior of the boat. In an embodiment, the container is shaped to receive a kayak. In this embodiment, the container shape conforms to the open area of the kayak.

The storage device has a substantially flat base that is proximate to the vehicle and substantially shaped like the top outline of the boat. The base of the storage device may be flat or may follow the contour of the gunwale of the boat. The base is attached to the racks (usually 2) of the vehicle by any releasably attachable means. In an embodiment, the storage device is attached to the racks by a clamp with a releasable toggle.

All or a portion of the base may be covered by a pad. The pad is made from any material that prevents or decreases objects placed in or on the container from sliding when the vehicle is in motion. The pad may (or may include means to) keep air, water, insects and the like out of the container. The pad comprises means to tie down objects placed in the container. Tie are any restraining device, such as but not limited to hooks, cords, netting, hook and loop fasteners, indentations, and the like. In an embodiment, the indentations are shaped to receive objects to prevent them from moving, such as parts for the boat (engine, motor, battery, seats, etc), accessories for the boat (oars, nets, bumpers, ropes, etc) sporting equipment (fishing gear, etc), and camping gear (cook stove, tent, sleeping bag, food, clothing, etc).

The storage device walls are attached to the base and conform generally to the interior walls of the boat. The invention comprises at least one bench to provide seating in the boat during use. The boat part comprises a mount for a motor or engine.

In an embodiment, the storage device comprises a flange that extends outward from the walls that form the container. The flange comprises a rim. A gunwale of the boat rests on the flange. The rim extends along each side of the base to act as a hinge to engage the gunwale when an opposite side of the boat is angle lifted from the base. An advantage of the invention is that the rim engages the gunwale of the boat, thus eliminating any requirement for additional hardware and allowing the boat to be easily and quickly removed from the storage device.

The boat is attached to the storage device by securing means. The securing means is any device that easily releasably attaches the boat to the storage device. Any fastener, such as but not limited to cam handles, a locking hasp, interlocking plates, retaining nuts and collars, pins, anchors, lock bushings, padlocks, ropes and the like may be used to secure the boat to the storage device.

The securing means comprises locking mechanisms, which work to attach the boat to the container. The securing means are located so an adult can easily access to detach the boat. In an embodiment, the securing means are located on a portion of the side wall of the boat. The locking mechanisms typically extend though the wall of the gunwale of the boat and locks to a portion of the corresponding side wall of the storage device. The locking mechanism is placed so that the boat fits over the container to create a water-tight volume from the container base to the inside bottom of the boat. When all locks are opened, the boat is released, the securing means remains attached to the storage device, and the boat may be lifted off of the container. Securing means may also be employed in corresponding openings in the boat and container through which a rope, a detachable pad lock, and the like are inserted to secure the boat to the container. In an embodiment, the boat comprises exterior surface elements on each exterior side of the boat to assist in removing the boat from the container. In an embodiment, two locking mechanisms are located apart from each other on each side of the device.

In an embodiment, the locking mechanisms may comprise a hinge. The hinge allows the boat to angle away from the container when one side is unlocked and the other side is attached. A user can then access items stored in the container, and relock the boat to the container. An arm props the opened side of the device open when unlocked. The walls of the container comprise access means, including but not limited to a segment of the side wall that is lower than the remainder of the wall, a door, a sliding panel, a removable segment, a hinged segment, and the like. The access portion is an opening that allows a user to see into or place objects in the container without reaching over the top of the wall.

In an embodiment used for kayaks and canoes, the side walls of the container are joined at a bow end and a stern end. In an alternate embodiment, the storage device comprises a stern wall. In this embodiment, the side walls are not directly attached, but are attached to opposite ends of the stern wall. The back wall extends upward from the edge of the base that is toward the back of the vehicle roof and generally conforms to the inside of the stern of the boat. Each storage device side wall is joined to an upward extending opposite lateral side of the back wall.

In an embodiment, a container cover is used when the boat is removed from the storage device. The cover protects items in the container when the boat is removed from theft and the elements. The cover is formed from a tear-resistant, waterproof or water resistant flexible material shaped or fitted to securely cover the container when the boat is removed.

The storage device is formed from any lightweight durable material, such as polymers, rubbers, metals, composites thereof, or any other suitable heat resistant material that is generally resistant to breakage. The container is open at the top of the side and back walls, and the container walls do not extend to the floor of the boat. The storage device may be formed with structures to increase durability, such as, but not limited to, honeycomb structures, indentations, struts, ribs and the like.

The volume of the container is less than the volume of the interior of the boat and may be loaded with items such as clothing, personal items, equipment and gear. The interior of the container is not segmented, thus offering the advantage that objects may be carried that extend the entire length of the container. Because the container is lidless, objects that extend over the top edge of the container that fit within the boat may be transported when the boat is attached, and objects larger than those that fit within the boat may be carried if the boat is not attached. With the boat attached, the container is water tight and secure. When the vehicle is driven without the boat on the storage device, the container is aerodynamic.

The boat of the present invention fits over the container and is securely detachably attached to the storage device. An important advantage of the present invention is that, because the boat fits over the container, the boat gunwale does not have to be a straight plane. The boat is formed from any lightweight, rigid, durable material, such as metals, polymers, fiberglass, resins, compounds and composites thereof, and the like. The boat may be motor or engine driven and includes means to mount an engine or motor. Being formed and manufactured from lightweight, rigid, and durable materials provides additional advantages, such as the boat being easier to remove and easier to attach than other vehicle top boats.

The boat of the present invention is formed with additional elements, such as handles or an exterior surface element to make it easy to lift the boat off of the container, seating and the like. The handles may be used to attach bumpers or other gear to the outside of the boat. Seating for the boat or kayak is included. The handles and benches/seats are formed from a similar material as that used to make the boat, or from any lightweight durable material. The handles may be openings that correspond to openings in the storage device and are use to secure the boat to the storage device using a padlock, a rope, a tie, and the like.

The storage device and boat may be used without the vehicle to securely store gear and equipment, such as in the off season or when using the vehicle for other purposes.
